Muscles of the Hip and Thigh

The tensor fasciæ latæ is broad, and its fleshy part reaches almost to the patella.

The gluteus superficialis has a sacral head only; it blends with the biceps femoris.

The gluteus medius has a small lumbar part which does not extend so far forward as in the horse. The deep part (Gluteus accessorius) is pretty clearly marked.

The gluteus profundus is extensive, reaching nearly to the external angle of the ilium.

The biceps femoris has a narrow origin from the sacro-sciatic ligament and tuber ischii. It ends below like that of the ox.

The semitendinosus resembles that of the horse.

The semimembranosus has two insertions as in the ox.

The sartorius has two heads of origin, between which the external iliac vessels are situated. The inner arises from the tendon of the psoas minor, the outer one from the iliac fascia.

The graciles are united at their origin even more than in the ox.

The pectineus is well developed and is flattened from before backward.

The adductor shows no division and is partially fused with the gracilis. It ends on the femur just above the origin of the gastrocnemius.

The quadratus femoris is large.

The obturator externus resembles that of the horse.

The obturator internus is extensive and strong; its tendon emerges through the obturator foramen.

The gemellus is fused in part with the obturator internus.

The quadriceps femoris is more clearly divided than in the horse, and its action is transmitted by a single patellar ligament.

The capsularis is absent.
